Meaning of VERNIER in English


or vernier caliper

Instrument for making very accurate linear or angular measurements.

Introduced in 1631 by Pierre Vernier (с 1580–1637), it uses two graduated scales: a main scale similar to that on a ruler, and a specially graduated scale, the vernier, that slides parallel to the main scale and enables readings to be made to a fraction of a division on the main scale.
